Estudio y modelización de la fase de estirado en el proceso de embutición profunda sobre chapa de acero bajo en carbono con revestimiento multicapa de polímero

El proceso de estirado es la fase más crítica en la fabricación de una lata metálica. Existe la posibilidad de utilizar como material de partida una chapa de acero revestida por tres capas de polímero, pero este revestimiento no debe de fallar ni romperse bajo ningún concepto, para que pueda ser considerado como una alternativa viable y eficaz al proceso tradicional. Durante el estirado, las deformaciones son muy severas y existen altas presiones entre la matriz y la pieza. La reducción de espesor que se produce en el estirado hace que se genere una gran cantidad de superficie nueva. El deterioro del revestimiento en esta delicada operación podría provocar que el alimento o bebida almacenado en el interior de la lata tuviese un contacto directo con el metal. Como puede apreciarse, la clave fundamental en el uso de láminas de acero revestidas por capas de polímero en la fabricación de latas radica precisamente en la supervivencia de éstas al proceso del estirado. Otro aspecto muy importante es la rugosidad superficial de la nueva superficie generada, porque la lata se ha de poder decorar perfectamente. El hecho de cambiar el método de fabricación tradicional de las latas de bebidas o de los envases metálicos, y utilizar en cambio este nuevo material previamente revestido, permite una notable reducción en la contaminación medioambiental generada al evitar la formación de compuestos orgánicos volátiles (COV's) en la fabricación de las capas de polímero. Esta reducción también es mayor al no utilizar lubricantes adicionales, ya que las capas de polímero sólido previamente revestidas sirven de auto-lubricante del proceso de la embutición. Estos objetivos, junto con el de la mejora de las características mecánicas y la adhesión de la pintura o imprimación decorativa, se consiguen con la utilización del material con el que se trabaja. Se ha realizado una búsqueda bibliográfica sobre el proceso de estirado en materiales revestidos, y algunos autores utilizan y argumentaSellés Cantó, MÁ. (2009).

An Efficient COVID-19 Prediction Model Validated with the Cases of China, Italy and Spain: Total or Partial Lockdowns?

[EN] The present work develops an accurate prediction model of the COVID-19 pandemic, capable not only of fitting data with a high regression coefficient but also to predict the overall infections and the infection peak day as well. The model is based on the Verhulst equation, which has been used to fit the data of the COVID-19 spread in China, Italy, and Spain. This model has been used to predict both the infection peak day, and the total infected people in Italy and Spain. With this prediction model, the overall infections, the infection peak, and date can accurately be predicted one week before they occur. According to the study, the infection peak took place on 23 March in Italy, and on 29 March in Spain. Moreover, the influence of the total and partial lockdowns has been studied, without finding any meaningful difference in the disease spread. However, the infected population, and the rate of new infections at the start of the lockdown, seem to play an important role in the infection spread. The developed model is not only an important tool to predict the disease spread, but also gives some significant clues about the main factors that affect to the COVID-19 spread, and quantifies the effects of partial and total lockdowns as well.Sanchez-Caballero, S.; Sellés Cantó, MÁ.; Peydro, MA.; Pérez Bernabeu, E.

An Economical and Environmental Alternative to Traditional Can Manufacturing Using a New Pre-Laminated Steel

[EN] Metal containers are the most commonly used packaging worldwide in both the food and beverage industry. Some manufacturing processes in the canning industry include multi-step transformations that take large aluminum or steel coils and make them into two or three-piece cans. During this process, the containers are sprayed to obtain a better surface for the contents; however, this spray produces volatile organic compounds (VOC). This paper presents a new and environmentally friendly can manufacturing method, which uses a novel pre-laminated two-layer polymer steel. As experimentally proven, this innovative polymer-coated steel successfully withstands every manufacturing requirement. The specimens were tested in an ironing simulator, measuring roughness and friction coefficients. The development of an upper bound ironing model, along with a supporting neural network, allows an insight into the design of new materials for can manufacturing.Sellés Cantó, MÁ.; Schmid, SR.; Sanchez-Caballero, S.; Ramezani, M.; Pérez Bernabeu, E.

Failure analysis of a plastic modular belt in-service

[EN] In this study, an analysis of the possible causes of the failure in-service of a section of a plastic modular belt was conducted. The study begins with a reproduction of the service conditions in a traction gear. An analysis of the fracture surfaces revealed the existence of defects in the interior of the parts. With the aim of determining the origin of the imperfections and their influence on the failure, an exhaustive mechanical and rheological characterization of the material was carried out. The development of an FE Analysis established that the reduction of the tensile strength of the part due to internal defects was around 70%. Tests also showed that the most stressed area was the area where the most defects appeared. A simulation of the injection process showed that the defects are caused by the geometry of the part, leading to the conclusion that its failure was caused by bad dimensioning of thicknesses.Sanchez-Caballero, S.; Sellés Cantó, MÁ.; Ferrándiz Bou, S.; Peydro, MA.; Oliver, B.

Nuevas perspectivas en la docencia y el teletrabajo

El impacto de las tecnologías ha llegado a la redefinición de una sociedad basada en una producción agrícola para dar lugar a la producción del conocimiento. La nueva sociedad de la información exige empresas cada vez más ágiles, más globalizadas y competitivas, sensibles a los cambios y que reaccionen rápidamente ante las variaciones del mercado, donde ya no importa la ubicación física de la misma ya que la tecnología de la comunicación permitirá subsanar la mayoría de los inconvenientes temporales. En una nueva era donde se da paso al poder del conocimiento que permite productos y servicios cada vez más dinámicos y personalizados parece haber terminado la producción en serie dando lugar a un proceso donde el trabajo sigue al hombre. Este nuevo concepto que se introduce en la era digital al que denominamos teletrabajo permite el acceso a fuentes de trabajo sin distinción de sexo, edad, ubicación y/o discapacidad física ya que gracias a las tecnologías disponibles y al buen aprovechamiento de las mismas podemos igualar las condiciones de acceso al trabajo para muchos que hoy no lo tienen. Este manejo de tecnología como email, video conferencia, navegar por Internet, telefonía, chat, es algo muy común e incorporado en su vida cotidiana para los niños de la actualidad y que seguramente lo incorporarán a su vida laboral cuando lleguen a ser profesionales. Por este motivo se necesitarán profesionales cada vez más ágiles y con destreza para ser competitivos en su vida personal y laboral y por lo tanto se necesitaran docentes con aptitudes y actitudes pro-activas que colaboren en el proceso educativo. En la actualidad la colaboración entre la Universidad y otras instituciones públicas y privadas en investigación y formación es un hecho concreto. Muchas empresas privadas y administraciones públicas se han acercado a la Universidad demandando servicios y ésta última a través de sus propios profesionales vuelca sus saberes a la comunidad realizando asistencia técnica a departamentos de Recursos Humanos, asesoramiento en los programas de formación, en el uso de materiales, en la didáctica, en la formación multimedia que facilita el autoaprendizaje, etc.Eje: Educación universitaria: Experiencias uso NTICRed de Universidades con Carreras en Informática (RedUNCI

Study regarding complex shapes manufacturing using CAM

In the case of complex cavities shapes, manufacture using classical methods proved to be a very difficult process. Classical methods imply splitting the part in many leveling planes, the distance between them being given by the depth of the cut and the feeding rate. The purpose of this paper is to present how cavities are made using CAM softwares, mainly SolidCAM and how fast this method is in comparison with the classical one. A mold cavity of a complex shape is presented as the example of this aspect. The cavity of the mold was made using 3 axes machine tool equipped with Heidenhain CNC control.Flavius, AA.; Sánchez Caballero, S.; Sellés Cantó, MÁ. (2012).

Analysis and review of different tools to calculate the production economics in injection molding

The purpose of this work is to make a small review of computer-aided software based mainly on the calculation of the injection molding cost. Only a representative portion will be discussed in this paper. An injection molding machine can produce thousands of pieces per day, depending on many factors. A small improvement in the cost per piece can have a significant impact on the industry. These factors have to be carefully considered by the software in order to make accurate estimations. A total of 5 programs are fully analyzed in this contribution, and this is useful to achieve good cost estimation for the injection molding process. The main characteristics and/or features of each of them are also described.Sellés Cantó, MÁ.; Sanchez-Caballero, S.; Pérez Bernabeu, E. (2014).
